Exo series dovetail mount for front sight

[Ekkie]

I'm looking for a measurement from an Exo series Excal. I'd like the distance from the center of the barrel (centerline of the shaft of the arrow) to the nearest edge of the dovetail mount on the riser.

I'm having a pin holder made that fits some easily purchased 3/16" square base brass pins. I've measured everything up, and the model I put together should work fine with my Middleton riser, but I'm curious if it'll also be useful for older Excals. If you want to see a few pictures of what I'm talking about, I started a thread on ArcheryTalk here: http://www.archerytalk.com/vb/showthread.php?t=4815169

Thanks in advance!

Thanks much! Basically what I measured from the Middleton riser.
